有许多田间或实验室的测定喜温植物相对抗寒性的方法。但都需花费大量时间或育种材料,在育种实践中有时很难普遍采用。因此,当前正研究快速而又不毁坏有价值选育材料的抗寒性鉴定方法。由于采用直接法鉴定植株抗寒性有许多困难,所以用实验室快速测定法就 There are many field or laboratory methods for determining the relative cold tolerance of thermophilic plants. But they all need to spend a lot of time or breeding materials, which is hard to be widely used in breeding practice. Therefore, cold hardness identification methods that are fast but do not destroy valuable breeding materials are currently under study. Since there are many difficulties in using direct methods to identify the cold resistance of plants, rapid laboratory tests
